Files page will not open

I just set up 2 different nextcloud servers side by side for my server and for my dad’s server. Mine seems to be working fine but the other won’t open the files page for some reason (Images of what I’m talking about). Basically, when I click on the folder icon the browser says “This page isn’t working right now. localhost didn’t send any data”

I had some issues with my PHP version during both installs, could it possibly be related to that? I may have just made some really dumb mistake because this is my first time using nextcloud and my Linux experience is limited so I am sorry if this is a stupid question!

Hello mate, hope you are doing well…

Which OS are you running? And also, which version of php and nextcloud did you install?

Have a nice day mate.
